Historic gardens are important parts of humanity’s built heritage within the designed landscape, providing many environmental, economic and socio-cultural benefits. Management is a key part of their conservation, perhaps the most difficult because it is costly, must be continual, and requires a skilled workforce. This systematic review looks at the literature addressing historic garden management, with special attention regarding the social, economic and environmental aspects of sustainability. Academic studies on this subject come from many different disciplines, making it both stimulating and fragmented. It is now time to consolidate these interdisciplinary efforts into a clear vision, including a framework of key themes and research methods so as to better coordinate efforts and make the information and innovation generated more accessible to the garden managers “in the trenches”. With this aim, reviewed studies are classified according to 10 criteria: supply or demand orientation; management phase involved; primary sustainability processes addressed; geographic criteria; number of sites covered; policy documents referred to; kind of data collected; study methods employed; possibility of bias specifically regarding historic gardens; garden use. An analysis of these criteria shows that historic garden management literature focuses on describing the gardens themselves, with few studies interested in the people supporting them. Future research should follow recent policy documents’ lead and pay more attention to community value and involvement.

This paper presents a study of traditional netting materials subjected to disinfecting chemicals during fish farming and treatment of net cages. A series of tests were performed in order to study the effect of various concentrations of disinfecting chemicals on the tensile strength of Raschel knitted Nylon netting materials. Simulated spill of diluted hydrogen peroxide (HP) to the jump fence during de-lousing did not affect the strength of the applied new and used knotless nylon netting samples. Hydrogen peroxide reacted with biofouling forming gas bubbles, but this did not result in reduced netting strength. The performed tests did not indicate any effect on netting strength from a simulated single, traditional bath disinfection as performed at service stations applying the disinfectant Aqua Des (AD) containing peracetic acid (PAA). However, increasing the AD concentration from 1 to 10% resulted in a strength reduction of 3–6%. Simulated spill of concentrated AD on the jump fence of a net with copper coating residuals resulted in a severe reduction in strength of 45%. This strength loss was probably a consequence of chemical reaction between copper and Aqua Des, and uncoated netting did not experience any loss in strength subjected to the same chemical exposure. These findings from application of AD should also apply to other PAA disinfection chemicals with trade names as, for example, Perfectoxid and Addi Aqua.

Sugar is an important economic commodity that is produced and consumed around the world. The impacts of different production methods differ on social, economic and environmental aspects. This research focuses on the economic trade- offs in conventional, organic and Fairtrade sugarcane production in India and sugar beet production in the Netherlands. Previous research provides insights into single production methods, but a complete comparison between different production methods is currently lacking. Data was collected using both literature research and interviews in the Netherlands and India. After developing a Multi-Criteria Analysis, it is concluded that organic sugarcane and Fairtrade sugarcane rank slightly higher than conventional sugarcane on the economic criteria. However, conventional sugar beet and organic sugar beet rank higher on all economic aspects, with conventional sugar beet ranking the highest. The main differences between the production methods can be seen in the innovation, and to a lesser extent the in the production.

Permasalahan yang dihadapi pembudidaya ikan dengan sistem intensif adalah meningkatnya limbah yang terakumulasi pada air dan sedimen. Limbah budidaya ikan pada umumnya berupa padatan dan nutrien terlarut pada air terutama nitrogen dan fosfor. Tujuan penelitian ini adalah mengkaji distribusi nitrogen total dan fosfor total pada budidaya ikan gabus secara intensif yang diberi eceng gondok Eichhornia crassipes dan probiotik (Pseudomonas aeruginosa dan Achromobacter insuavis). Penelitian dirancang menggunakan rancangan acak lengkap dengan perlakuan pemberian kombinasi eceng gondok dan probiotik (A), pemberian eceng gondok (B), dan pemberian probiotik (C), masing-masing perlakuan diulang tiga kali. Benih ikan gabus yang digunakan berukuran panjang 14,74 ± 0,01 cm dan bobot 25,53 ± 0,09 g dengan padat tebar 175 ekor/kolam (50 ekor/m3). Selama 90 hari masa pemeliharaan, ikan gabus diberi pakan berupa pelet dengan kandungan protein sekitar 30%. Jumlah pemberian pakan 5% dari biomassa dengan frekuensi pemberian empat kali dalam sehari (pagi, siang, sore, dan malam). Hasil penelitian menunjukkan nitrogen dan fosfor pada budidaya ikan gabus terdistribusi pada eceng gondok, sedimen, air, dan ikan. Eceng gondok menyerap nitrogen dan fosfor paling tinggi (P<0,05) dibandingkan air, ikan, dan sedimen. Laju pertumbuhan spesifik bobot (4,37 ± 0,01%/hari) dan biomassa (1,88 ± 0,01 g) ikan gabus tertinggi dicapai pada pemberian kombinasi eceng gondok dan probiotik. Hasil ini dapat dijadikan landasan untuk pengelolaan limbah nitrogen dan fosfor pada budidaya ikan gabus secara intensif.One of the problems in intensive aquaculture system is the the accumulation of waste in the water and sediment. Aquaculture wastes are discharged into the water in form of solids and dissolved nutrients which mostly consisted of nitrogen and phosphorus. The purpose of this study was to study the dynamics of total nitrogen and phosphorus in an intensive aquaculture media supplied with water hyacinth and probiotics (Pseudomonas aeruginosa and Achromobacter insuavis). The study was designed using a completely randomized design with treatment combinations of water hyacinth with probiotic (A), water hyacinth (B), and probiotic (C). Each treatment consisted of three replications. The seeds of snakehead used had body length of 14.74 ± 0.01 cm and weight 25.53 ± 0.09 g, stocked in ponds with stocking density of 175 individuals/pond (50 individuals/m3). During 90 days of rearing, the fish were fed with pellet with protein content of 30%. The amount of feeding was 5% of the biomass with feeding frequency of four times a day (morning, afternoon, evening, and night). The results showed that the produced nitrogen and phosphorus in the snakehead cultivation were distributed to water hyacinth, sediment, water, and fish. Water hyacinth absorbed most of the nitrogen and phosphorus compared to water, fish, and sediment. Higher specific growth rate (4.37 ± 0.01%/day) and biomass (1.88 ± 0.01 g) of snakehead were achieved in combination of water hyacinth and probiotic treatment. These results can be used as a basis for the management of nitrogen and phosphorus wastes in an intensive fish farming.

Feeding a growing global population using conventional agricultural practices is leading toadverse environmental impacts. There is a call for alternative forms of agriculture that address social,economic, and environmental aspects of sustainability. Permaculture is a holistic design frameworkthat incorporates sustainable agricultural practices, potentially improving livelihoods. This studylooked at the challenges and benefits of permaculture in improving rural livelihoods in Zimbabweand South Africa. We used semi-structured interviews to collect data. Permaculture contributed over40% to total income for participants in both countries. However, permaculture was not the dominantsource of income and periodically straddled multiple livelihood strategies. The main benefits ofpermaculture were identified as improved human health, increased resilience to environmentalchanges, and reduction of input costs. The key challenges included high labour input, infestationof pests and diseases, and lack of knowledge on permaculture practices. Although permaculturepresents significant challenges, its integration with other forms of sustainable agricultural practicescan contribute to improved rural livelihoods.

<strong>Growth Rate of Humpback Grouper Cromileptes altivelis Cultured in Floating Net Cages.</strong> Humpback Grouper <em>Cromileptes altivelis</em> fish farming has good opportunities in the future, although still experiencing problems in its cultivation. One of the parameters that needs to be considered is the stocking density associated with the cage area. The purpose of this study was to determine the appropriate stocking density to generate optimum growth of Humpback Grouper cultivated in floating net cages. The study was conducted using the experimental method with 3 treatments and 3 replications. There were 9 cages used with the size of 1 x 1 x 1.5 m3 and a mesh size of 0.5 inches. The study was conducted in the waters of Banda Neira, Maluku, with the condition of the waters during the experiment, such as salinity which ranged from 33.2 to 34.6‰, water temperature ranged from 25 to 31°C, pH ranged from 7 to7.5, current speed 0.32–3.97cm/s, and water clarity was 14.29 to 20 m. The feed was trash fish given twice a day, in the morning and afternoon as much as 10% of total body weight of fish. After 4 months of cultivation, the absolute growth was best demonstrated by the treatment with stocking density of 25 fish/cage, which was 18.22 g, while the lowest (13.25 g) was shown by the treatment with stocking density of 75 fish/cage. The specific growth rate in the treatment of 25 fish/cage reached 1.34%/day, while the treatment of 50 fish/cage and 75 fish/cage reached 1.18%/day and 0.97%/day respectively.<br /><br /><br />
